CLOCK-FACE-MOUNTING MEANS.

Specification of Letters Patent.

Patented 0a. 21, 1919.

Application filed May 13, 1918. Serial No. 234,044.

To all whom it may concern:

Be it known that I, CHARLES CoHAN, a citizen of the United States ofAmerica, and resident of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented a new and useful Improvement in Clock-Face-Mounting Means, of which the following is a specification.

My invention relates to an improved. means of mounting clock faces upona clock 'works, wherein an object is to mount the face in a manner suchthat relative motion between the face and the clock works is positivelyprevented and wherein means are provided for quick detachment from andattachment to a clock works.

These and other objects are attained in the clock face mounting meansdescribed in the following specification and illustrated in theaccompanying drawing in which:

Figure 1 is a composite viewof the rear of a clock face and the front ofa clock works having elements of the mounting means embodying myinvention, mounted thereon.

Fig. 2 is a sectional view of the mounting means embodying my invention.

My improved face mounting means consists of a series of sockets 3, oneof which is preferably mounted at each corner of the front plate of theclock works, and a series of pins 4, one of which is mounted at eachcorner of the clock face in position to be received by the cooperatingone of the sockets 3.

Each of the sockets consists of a cylindrical body 5 having a recess 6therein, a latch pin 7 extending into the recess, a spring 8 carryingthe latch pin, and a knob 9 mounted on the spring and adapted tofacilitate withdrawal of the latch pin from the recess. A screw 10 andwasher 11 are provided for attaching the body to the front plate in themanner shown in Fig. 2.

Each of the pins 4 is provided with a base 12 which may be attached totherear surface of the clock face in a suitable manner, and a pointedend 13, back of which a. groove 14 is, located. The inner end of thelatch pin is beveled as shown in Fig. 2 to permit the tapered end of pin4 to pass it, the groove being located in position to receive the latchpin when the pin 4 is pushed into the recess 6.

In mounting the face in position it is but necessary to push the facelugs into position within the recesses of the socket until the latchpins engage the grooves. This looks the face in position with relationto the clock works.

In removing the face it is only necessary to Withdraw the latchpins sothat the pins 4 may be freed and the face thus permitted to be removed.

Having thus described my invention, what I claim is;

A clock face mounting means consisting of a series of sockets projectingforward from the front plate of a clock works, a series of spring pinsmounted upon the sockets, a series of grooved pins projecting inwardfrom the rear face of a clock face and in register with the sockets, andwhose grooves are adapted to engage the pins when the pins are pushedinto the sockets, whereby the face will be retained in position withrelation to the works.

In testimony whereof, I have hereunto subscribed my name this 9th day ofMay,

CHARLES COHAN. Witnesses:
